Hi,
Base on your description, you just want to reflect changes from A to B, but do not reflect changes on B back to A or recopy it from A to B.
I think both folder pairs action "Echo" and "Conribute" could satisfy your requirement. BTW, which version of SyncToy are you using? Would you please try to download the latest SyncToy v2.1 and have a try again?
Thanks,
Ping
